Abstract

It has become increasingly apparent in recent years that many of the small polypeptide hormones arise as products of structural genes that evidently are considerably larger than the secreted hormones (Steiner et al., submitted for publication; Tager and Steiner, 1974). These observations have stimulated considerable research activity in efforts to learn more about the biosynthetic mechanisms leading to the production of the small peptide hormones and to seek explanations for the existence of their larger precursor forms. On the basis of the evidence presently available it may be concluded tentatively that there are probably many explanations for these forms rather than any single or pre-eminent one. In this report I will briefly review current information regarding these hormonal precursor forms, their structures and cleavage mechanisms, and then attempt to come to grips with the difficult question as to why these occur.
